For vibe coders

You built the app. It needs a backend.

AI app builders are very good at producing a working front end in an afternoon. The wall comes later, when it needs real users, real customers and data that outlives a redeploy. Aaly is the part that goes behind it.

The wall, specifically

Nothing on this list is exotic. It is the ordinary set of things that separates a demo from a product, and all four are backend problems.

Sign-up and login that actually holds

Not a mock user in local state. Real accounts, hashed passwords, Google sign-in, sessions that expire and refresh.

Each customer seeing only their own data

The moment you have two customers, every read has to be scoped to the right one. This is where hand-rolled backends leak.

Data that survives a redeploy

Browser storage and a JSON file are not a database, and you find that out at the worst moment.

An API the next change doesn't break

Add a field and every screen that touches it needs to keep working, without you rewriting the parts that already did.

Use the AI you already pay for

Aaly does not sell AI credits and is not another app generator. You bring the coding agent you already have (Claude Code, Cursor, Codex, or anything else that speaks MCP) and point it at Aaly. Your subscription to that agent is unchanged, and there is no second, credit-metered bill just to have a backend.

Connecting is one URL. You paste https://mcp.aaly.io into your agent as a custom connector and approve it in the browser. No API key to generate, copy, or accidentally commit.

Then describe what you are building

Tell your agent what the app is. It creates the entities, fields and relationships through Aaly, and the REST API for all of them is live immediately. No deploy step, no migration to write, no schema file to keep in sync with anything.

What you get that you did not ask for

Every Aaly project is multi-tenant from the moment it exists. Records belong to a customer, and the platform enforces that on every endpoint rather than leaving it to a filter someone has to remember. A request carrying one customer's token cannot read another customer's record. That is the single failure most hand-built and AI-generated backends ship with, and it is not something you have to configure here. How that works →

Alongside it: authentication with Google sign-in and rotating refresh tokens, validation from the same definition, typed relationships, file uploads, filtering and facets, your own Python on the request lifecycle when you need it, and a live OpenAPI spec your agent reads instead of guessing at. The full list →

Is this you?

✓

You are building something with customers in it, not a single-user tool

✓

Your data has real structure and relationships, not a pile of documents

✓

You expect the schema to keep changing as the product does

✓

You want your agent working against a production backend, not a mock

✓

You do not want AI-generated backend code to become your maintenance job

✓

CRM, helpdesk, booking, inventory, ops tools, internal dashboards

Running client projects rather than one product? There is a page for that →

Where Aaly is not the answer

If the app needs live chat, presence, or anything that pushes updates to a screen without the client asking, Aaly does not do that today and it is not on the roadmap. Same for scheduled or recurring jobs, roles and permissions inside a single customer, and importing an existing dataset from CSV. Every gap, with a workaround for each →

Free tier: 100,000 requests a month and 2 projects. No card.

Enough to put something real in front of real users, rather than a trial that expires while you are still building.
